1. INTRODUCTION, SPECIFICATIONS, APPROVALS, &

COMPLIANCE

Teledyne API’s Model N901 Hydrocarbon Analyzer is a high-sensitivity instrument that

uses Gas Chromatography (GC) with a Flame Ionization Detector (FID) to measure the

concentration of Total Hydrocarbons (THC) and Methane (CH

) in air, and calculates the

difference to provide an accurate non-Methane (non-CH

) concentration reading. The

range and performance of the N901 are tuned specifically for use in ambient air quality

monitoring assessments.

The Model N901 is designed for simple operation and maintenance with a modular

hardware and electronics architecture. A long-life stainless-steel fritted filter is used at the

sample intake to effectively remove particulate matter without introducing any gas-phase

measurement artifacts. Instrument operation, calibration functions and data handling are

all automated and controlled using the internal NumaView

Software (NVS) interface,

without the need for an external PC. Additionally, NumaView

Remote Software can also

be used for remote communications, for access to the graphical user interface, for

downloading data, and for other operations.

The section on Principles of Operation (Section 6) provides more information on the

method and the functional details.

2. GETTING STARTED

This section addresses unpacking, connecting, and initializing the instrument, getting an

overview of the menu system, and setting up/configuring the functions.

UNPACKING

CAUTION - GENERAL SAFETY HAZARD

To avoid personal injury, always use two persons to lift and

carry the analyzer.

ATTENTION

COULD DAMAGE INSTRUMENT AND VOID WARRANTY

Printed Circuit Assemblies (PCAs) are sensitive to electro-static

discharges too small to be felt by the human nervous system. Failure

to use Electro-Static Discharge (ESD) protection when working with

electronic assemblies will void the instrument warranty. Refer to the

manual, Fundamentals of ESD, PN 04786, which can be downloaded

from our website at http://www.teledyne-api.com

ATTENTION

COULD DAMAGE INSTRUMENT AND VOID WARRANTY

Do not operate this instrument without first removing dust plugs from

SAMPLE and EXHAUST ports on the rear panel.

Note

Teledyne API recommends that you store shipping containers

and

materials for future use if/when the instrument should be

returned to the factory for repair and/or calibration service. See

Warranty statement in this manual and Return Merchandise

Authorization (RMA) on our Website at http://www.teledyne-

api.com.

Verify that there is no apparent external shipping damage. If damage has occurred, please

advise the shipper first, then Teledyne API.

Included with your instrument is a printed record of the final performance characterization

performed on your instrument at the factory. This record, titled Final Test and Validation

Data Sheet, is an important quality assurance and calibration record and should be placed

in the quality records file for this instrument.

14 Teledyne API N901 HC Analyzer 092910910A DCN8375

With no power to the unit, carefully remove the top cover of the instrument and check for

internal shipping damage by carrying out the following steps:

1. Carefully remove the top cover and check for internal shipping damage.

a. Remove the screws located on the instrument’s sides.

b. Slide the cover backward until it clears the instrument’s front bezel.

c. Lift the cover straight up.

2. Inspect the interior of the instrument to ensure all circuit boards and other

components are intact and securely seated.

3. Check the connectors of the various internal wiring harnesses and

pneumatic hoses to ensure they are firmly and securely seated.

4. Verify that all of the optional hardware ordered with the unit has been

installed. These are listed on the paperwork accompanying the instrument.

WARNING – ELECTRICAL SHOCK HAZARD

Never disconnect PCAs, wiring harnesses or electronic

subassemblies while under power.

VENTILATION CLEARANCE

Whether the instrument is set up on a bench or installed in a rack, be sure to leave sufficient

ventilation clearance.

COMPONENT FUNCTION

AIR IN

Connect an air source free of hydrocarbon and moisture. The pressure must be between

45-55 PSI. The air consumption is 350CCM

AUX IN*

Connect clean zero air or Nitrogen with pressure between 65-75 PSI to actuate the switch

valve. It is possible to connect both CARRIER IN and AUX-IN ports on one line. The

consumption of the Aux In is 1CC per actuation

FID EXHAUST

Keep this port clear and open in a well-ventilated area for output from the FID, which is

primarily air and some water vapor and other combustion byproducts. If instrument is in an

enclosed or poorly ventilated area, vent this port with shortest line possible with the largest

inner diameter possible in order to prevent back pressure to the detector.

CARRIER IN*

Connect UHP Nitrogen (N

) gas (99.999% purity). The pressure supplied must be

between 45-70 PSI. The gas consumption is ~20 CCM.

SAMPLE IN

Connect a gas line from the source of sample gas to the externally mounted filter.

Calibration gas can also enter here, at ambient pressure, on units without the pressurized

valve option installed.

SAMPLE EXHAUST

Connect an exhaust gas line of not more than 10 meters long here that leads outside the

shelter or immediate area surrounding the instrument. The line must be ¼” tubing or

greater.

Cal Out

For use in calibration when valve options installed. Connect the output to the Sample In

port with Tee fitting to vent the extra gas

Cal In

For use in calibration when valve options installed. The Calibration gas that connects to

the ports should be 15PSI ± 2PSI

FUEL

Connect UHP Hydrogen (H

) gas (99.999% purity) with pressure between 45-55 PSI. Fuel

consumption is ~35 SCCM while flame is on. (Fuel line is shut off during Standby mode to

minimize fuel consumption).

Cooling fan

Pulls ambient air into chassis through side vents and exhausts through rear.

Power cable

connector

Connector for three-prong cord to apply AC power to the analyzer.

CAUTION! The cord’s power specifications (specs) MUST comply with the power

specs on the analyzer’s rear panel label

Power

On/Off

Switch

CAUTION! Prior to powering OFF, use front panel button for “soft” power-down of internal

components.

Fuse drawer

For circuit protection.

Model/specs label

Identifies the analyzer model number and provides power specs.

DIGITAL I/O Option

For remotely activating the span calibration mode.
